Whole Foods CEO John Mackey, vindicated in an SEC investigation of his anonymous postings on a Yahoo message group, is back blogging again at the company's web site. His first post explains his view of the incident with a second from a commencement speech he gave.

He said the SEC "matters now are completed with the board affirming theircomplete support for me and the SEC recommending that no enforcement action be made against Whole Foods Market or me. "

Mackey previously had a lively blog with a lot of comments, so we look forward again to seeing what issues he raises.
